To all 'whom t may concern.'

Be 1t known that I,- Fnfinn E. VVINN, a citizen of the United States,residing at Haskell, in the county of Haskell and State of rleXas, haveinvented new and useful Improvements in Rotary Engines, oi which thefollowing is a specification.

This invention relates to rotary engines or inotors, and particularlytol that type einbodying mechanical features Wherehy air compressed in apart of the cylinders is fed t0 and mixed With hydrocarbon in suitableform and the mixture then supplied in relatively controlled charges to aremaining part of the cylinders for combustion and generation of powerto rotate a sha-tt coinmon to all thc cylinders 'and serving as theactuating means .for the compressing e1e ments and also as the powertransmitting medium.

' The improved engine or motor has been specially devised for driving amotor vehicle, such as an automobile or truck, and. one. Object thereofis to provide an engine a com i pact forin einbodyinga plurality offcylinyais v group will eli'ect ders arranged end to end and providedwith a common shaft entendi ng therethrough having rotating pistonsfixed at different angles thereon in the respective cylinders, and toarrange the cylinders in groups for alternate internal combustion andair coinpression in the respective aircompression in another group, andcapable ol" instant reversal' of operation to correspondiugly modify orchange the, compression L froup to the combustion group and change thedirection ot' the rotation of the main shaft by. a sim ple control. oftheignition means in the cylinder groups. Another object o'f theinvention is'to provide an engine or motor havingl grouped cvlinderswith'a common shaft therethrough with pistons fixed'thereon andindividually rotating in the individual cylinders and so arranged thatthe pistons' of the group of driving` cylinders will make one driving'lgroups so that one i stroke each for each revolution of the said shaftand give a resultant steady motion similar to a turbine drive. A furtherobject of the invention .is to produce a very high air compression inone group of the cylinders for service iu the remaining group ot'driving or .internal combustion cylinders, and to deliver the air in achamber common to all the cylinders wherein also the fuel is received inthe form of a spray which is quickly changed to a vapor by the highspeed and whirling motion of the air' I and thoroughly mixed with thelatter, and thus make it possible to dispense with the usualCarlini-eter attachments or system.

lV ith these and other tages in View, the invention consists in theconstruction and arrangement' of the several parts which will be morefully hereinafter described and claimed. l

120, one with relation dierentiation 1n vanular'mounting of the -nervportion of the This particular preferred application, however, does notexclude the improved motor or engine vfrom any other adaptation that maybe desired.

ssentially the motor or engine comprises six cylinders divided into twogroups, 5, 7, 9, and 8, 8, and 10, these groups being shown in thedrawings to operate respectively as internal combustion or driving, andair comlnstead of six cylinders, the num er may be increased to eight,twelve, or any corresponding multiple. The cylinders are formed ordeiined by opposite end walls 11 and 12, a central group dividing wall13 and cylinder partition walls 14,

together with cylinder inclosing casings or sides having cylindrical orcircular piston chambers 16 of suitable dimensions, the wall 13 being4tl-iicker than the remaining All of walls and cylinder casings or sidesare suitably connected or joined in a strong and durable manner, and thejoints formed between these several parts will be rendered tight andnon-leakable by introducing therein any preferred form of packing,washer, gasket lor other joint sealing means. The walls and casings orsides also extend above the location of the piston chambers in thecasings, and will be constructed as hereinafter specified to provide foracnessories included in the general organization of the improved motoror engine. f

Extending through all 14: in suitable bearing means and in bear.- ings17 provided as parts of the end walls 11, is a main orpovwer shat 18which centrally passes through the cylinder chambers 16, and carriespistons 19, 20 and 21 in the chambers of the respective cylinders, 5, 7and 9and pistons 22, 28

chambers ot the respective cylinders 6, 8 and 10. The pistons 19, 2G and21 are all arrangedat diii'erent angles, or, at an langle' of to theother. r1`his the wallsl 13 and pistons is simi arly and successivelycarried out inv the arrangement of the pistons 22, y23, and

As all the pistons are duplicates in construction, a speciic descriptionof one will sufice. Each piston comprises ,essentially a mediumly hardmetal body 25 preferably of oval f 'rm and fixed eccentricaily on themain or 'power shaft 18, the body bein@r enveloped lby a hard metal wearsheat or casing 26. The adjacent sides of the end and partition walls ofthe cylinders above and below the main or power shaft are formed withrecesses 27 to receive the inbody 25 which is thicker than the remainingouter portion of the Said body, the outer' or thinner portion 28 ofthehody movingor rotating in a more confined outwardly by cross springs and24Cv in the' space between the cylinder and partition walls. The outerthinner portion 28 of the body 25 continues to the outer smaller end ofthe piston and has two side packing;- plates 29 nioi'ably set thereinand pressed 3() seated in said outer smaller end in suitable relation toset up a yielding cont-act between the plates 29 and the adjacentpoitions ot the inner sides ofthe said end and partition Valls. By meansof these packing plates a tight working joint of a non-leakablecharacter is maintained between the opposite ends of the outer portionof the piston and the adjacent walls. In the outer reduced or smallerend ofwthe piston between the plates 29, sockets '3'lareformed toreceive inwardly projectingstems 32 of a packing bar 33 which extendsfully over the outer reduced end of the piston and continually bearsagainst the inner surface of the side of the piston chamber. The bar 33is given a uniform outward and yielding projection by springs 84surroimding the stems 32 in the sockets 3l, Said springs having theiropposite eX- tremities 'respectively bearing against the bar and innerend walls of the sockets. The sockets also have oil ducts or bores 35extending thereinto and outwardly. through the sheath or casing 26. Theshaft 18 is also lubricated by means of ducts or bores 37 extendingtherefrom outwardly through the walls l1, 13 and lfhllateral orsubsidiary bores or ducts running from the ducts or bores 36tonditlerent portions of the opposite sides oli all the pistons andtheplates 222 thereof. The bores are supplied with suitable lubricant bycups 38 in communication therewith and mounted on the eX-. teriorportions of the walls 11, 13 and 14.

In, each cylinder above each piston is a swinging. cut-oill abutment 39"extending fully across the width of the cylinder chamber, the abutinentsbeing in reverse positions the two groups of cylinders '5, 7 and 9, a" d6, 8 and 10 to provide for reversal of the operation of the motor orengine and particularly the shaft 18. All of theabutments 39 arevsimilar in construction and have a like mounting in the cylinders.- Theupper portion of each cylinder to one side of the vertical centerthereoi' has acylindrical seat 40 formed therein to receive a,. jointtrunnion l1 at the outer end of theabitment 39, and from said seat arecess (t2 extends inwardly through the upper portion of the cylinderand opens downwardly"'intov vthe piston chamber,

said recess havin the lsame As contour as the abutment' 39 whicV [is:ressed ment 39 lis ot concave cnntour-"a dghas an gages' y 1 lwhereby athorough arc corresponding to and operating to regularly com-plete thecircular contour `of the side wall of the piston chamber and with whichthe outer reduced'end of the piston has contact. The abutment 39 has aninner free end'44 which is reduced and so shaped that a piston engagingangle is formed, the inner concave side 43 and a portion of the reducedend 44 including the piston engaging angle 45 being covered by a. hardmetal wear sheath or `casing 46. vThe angle 45 with its 'sheath orcasing 46 is at all'times held in contact with the sheath or casing 26and the packing bar 33 through the medium ot a plun ger 47 bearing onthe upper side ot'- the abutment 39 adjacent to the trunnion 41, saidplunger thereof being disposed at an anglev oi inclination to providefor a practical contact thereof with the abutment'in view of themovementand variable position of the latter. The plunger 47 mounted in acylindrical casing 48 .secured in and extending upwardly and outwardlythrough the piston cylinder. This casing 48 has alowerl guide member 49therein for the plunger, and in its upper end said casing is alsoprovided with an adjustable` screw plug 50 formed with 'a centrallyprojecting tubular stem 5l within the casing and into 'which the upperportion of the plunger movably extends. The plunger 47 has anintermediate stop or collar 52, and betweenthe latter and the plug 50 aspring 53 is mounted and exertsl a strong downward expelling, pressureon the plunger and the abutment 39 'through the plunger. The tension ofthe spring 53 may be regulated as found necessary by adjusting the plug50 which is exteriorly exposed in the outer end of the'cylindricalcasing 4H. The abutment 39 has a lubricant duct or bore 54 extendingthrough the same and also through the trunnion 41, and is supplied by anintersecting outwardly opening d'uct or here in the Ipiston cylinder,the said duct or bore 54 being in feeding communication with the wall.ducts hereinbt'it'ore described.

The duct or bore 54 alsointersects with and opens at its inner terminalinto a downwardly inclined outlet duct 56 through the inner reduced end44, anglel 45 and sheath or casing 46 of the abutment 39, the duct orbore being always lopen to the outer surface of the sheath or casing 26of tliepiston and lubrication is up between the angle and portion ot'the sheath. or casing 46 thercovcr and the piston to produce easymovement of the reduced end of thc abutment and its sheath over thepiston sheath or casing 26 and thus reduce wear on these parts. the ductor bore 5G is located slightly in rear et the` maximum projection of theangle 45 and the sheath or casing 46 of the abutment and the supportingparts .ating cylindrical charge The lower outlet of' 39 to obviatecloggingthe said outlet and obstructing' the through to the sheath orcasing 26 of the piston.

The. -walls 11, 13 and 14 continue above the cylinders and arevreducedin width to provide upper substantially rectangular extensions 57, andbetween these walls casings 58 are interposed and tightly jointedtherewith at their oppositev ends, as shown by Fig. 3. In the lowerportions of the extensions 57 and the casings 58 a circular valvechamber 59 isv formedl and extends full length of the motor between theextensions of the end walls 11 and 12, and extending through the top.portions of the cylinders below and communicating with the abutmentrecesses 42 are vertical passages. 60. Iiithe upper portions `of theextensions of the walls 14 and extending .through the latter in similarstructure on opposite sides of the dividing Wallv 13 are two chambers 61and 62 divided by a central vertical partition 63, the lower portions of.the chambers being open respectively, as at 64 and 65, to recesses 66,`there heilig one of these recesses to each cylinder and piston chamberbelow. The partition 63 extends downwardly through and divides therecess 66 into two parts, the said divided 'recesses opening' into theupper portion of the valve chamber 5S). Over the chamber G1 is at therear and the chamthe cylinders 5 7' and 9V passage ofthe lubricant there-Y ber 62 at the front, and over the cylinders- (i, 8 and 10 thepositions of these chambers f formation of independent ducts or com-'nmnicating passages 67 and 68 'formed in the upper extension. ot thedividingwall 13, as shown particularly by Figs. 2 and-3. Both ot' thechambers 61T and 62 receive compressed air from the cylinders acting asair con'iprcssors, but only one of the chambers, namely chamber 61,receives the' fue] in a 'manner which will be hereinafter explained, andin view of the open bottom construction of the chambers and the recesses66 and valve chamber 59 hereinbefore explained, the compressed air fromthe cylinders acting as compressors will be forced upwardly into bothchambers 61 and 62. In the valve chamber 59 is a continuouslyopercontrolling valve 69 having at intervals throughout the length.thereof between the extensions of the end walls 11 and 12 channels 70and 71` the channel 71 being of less width than the ehannel 70 and thetwo channels separated by with such packing devices as may 'be foundcompression 'from the group t5 ythrough the upper portion necessary toprevent leakage around the valve or between the latter and the wall othe chamber 59. The valve 69 also has a shaft 73 extending citrallytherethrough and projecting outwardly through the eX- tension of the endwall 12 where it is mounted in a suitable bearing 711 and on the outerend thereof is a Vsprocket wheel or other suitable driving element '75eiigaged by an endless chain or other belt Y6 also trained over asimilar device 78 keyed latter shaft projecting outwardly through asuitable bearing 79 in the end wall 12as particularly shown by Fig. 3.By means of this driving mechanism the valve 69 is actuated relativelyto the rotation of .the

shaft 18 and the pistons tliereo,'the channels '.70 and 71 of the valve69 heingso ar ranged around the valve or in such positions relativelytothe latter that the respective piston chambers will be regularlycharged with the mixture of air and fuel under conipression, or, thechambers 61 and 62 will be charged from the cylinders with air under ofcylinders operating as air compressors. The istons 19 by their variationin angular application to the shaft 18 will always be inproper positionin the group of cylinders arranged as internal combustion cylinders toreceive the charges successively thereagainst and he driven by theignition and explosion of said charges, and the pistons of the aircoinpressing cylinders in view of their successive singularity will alsoeffectively' compress air and force it upwardly into the chambers 61 and62 by the communicating operation of the valve 69 through the channels70 and 71 with the compressing cylinders and the said chambers 61 andG2. A storage tank `8O for fuel and air under compression is connectedby a pipe 81 to the chainher 61, an outwardly opening check-valve' 89 ofsuitable structure being ii troduced in the said pipe '81, and when thepressure in the chamber 61 is greater than a predetermined degree, thecheclrfvalve 89' is :forced o en and the compressed air having the nelmixed therewith is forced through the pipe 81'into the tan 80 andretainedlr or reservoir in this tank for starting1 purposes. To thebottom of they tank or reservoir 81 is connected and extendsr inwardlyof the one cylindei' casing adjacent thereto and connects with anelongated duct or bore 84. having communication by passages 85 with thevalve chamber of the passages and whereby in startirig up the mot/0r orengine the charges of fue and air in proper proportion and undercompression may be supplied to the valve chamber 59, a valve 86 beingintroduced in driving sprocket or on the sha-1518, 'the 59 at intervalsto one side,

The pipe 91 which. serves' as acommon supply pipe, connects with a conduit or pipe 99 through athree-way valve 100V in the latter. The conduit'or pipe 99 forms partor' a multiple pump organization which is constructed andA arranged topei'- forni different Apumping operations relativelyto separate parts ofthe motor or engine cylinders'v and the receiver 87. The pump 1,02 isconstructe as a reversible rotar Elmas-,sand throughwhich extends acom-Jinon shaft 106, the pump having a suitrble or inclosure 10? in which theseveral royliiulers are defined and the sha-ft 106 suitably mounted, thei wardly through one vthrough asuitable bearing 108, and has a sprocketor other drive wheel 109 thereon over which passes a belt 110, clearlyThe pipes 91 and 92 through the pipe 90 have communication i seated atthe juncture of the pipe 95 95 opened to permit When the pump having`four cylinders 101, 103, v

The drive Wheel 109 in the present instance isin the form of a sprocket and the belt 110 in the forni of a sprocketchain, said latter belt being also trained over a sprocket Wheel orother suitable driving' element 111 on the outer cX- treuiity ot theshaft 7 3 of the valve (Si) and whereby the operation of the pump willbe 'in timedrelation 'to the operation of", said valve. As hereinbeorenoted, the pipe 91 coi'xnerts with the conduit or pipe 99, the latterserving as means for conveying` to the pipe 91, when the valve 100 issuitably adjusted, the fuel constituents and .vater from the several`cylinders 101 to 10ft inclusive, and in each cylinder is a rotary piston112 which is disposed to rotate in a piston chamber 113 oi' eachcylinder, the pistons 112 being flisposed atl varying angles on theslial't 100 in the successive cylinder chambers. Above each piston 112 apair of abutments 1,1/1- and\115 is mounted, the-abutments having` theirinner ends normally engaging each piston and their outer ends fulmciiun'yed or positively mounted, at 116, in the ogn'iosite 'walls oieach cylinder chainbej. the abutments in double form beingf proded for areverse operation oi the chan'zber the o'ieration oi? the inoA orengine, h inbeore dest ibed, with non 'the pump eo-aets, and 'forms an s'e itial accessory. Each ot the abutments 1141 and 115 is constructedsimilarly to the abutineuts 32, hereinbefore. described, and has apressure means cooperating therel@ oni-before described in conwith theabutinents 39, and operatto maintain the ends oit the abutnients 111iand 115 in. continual contact with the outer surface of the pistons 112.Each piston chamber is provided with an inlet pipe 101 and an outletpipe 101, respectively communicat-ing` with the lower and upper portionsof each chamber and connecting; with the respective inlet pipes 101" ofthe chambers and cylinders 101 to 101 inclusive are supply pipes .117,118 and 119, between 'weich and the said inlet pipes 101a upwa openingcir valves 120 are iin i which. pre ent a 'back iiow of the liquid fromthe chambers oi the cylinders 101 to 101 inclusive to the sources otsupply, the outlet 1011D also each having upwardly (mening check valves121, similar to the valves 120, the valves 121 preventing,l back flowand back pressure affecting the chambers and the cylii'iders 101 to 1.01inelusive through. the said outlet pipes.- The in accorda nee. witi'.supply pipes Y1.17, 118 and 11i) nespectively engage or connect vwiththe gasolene supply source'122, the kerosene supply source 123 and thewater pipe 124 leading from a suitable tank or other sourceof supply125. A.

-cut-oii valve 126 is introduced in each pipe sive and each having alower elbow conneeted to the check valve 121 which is be-` tween thesame and the outlet 101,b of each cylinder. Each regula-tor consists oftwo uertica] tubular limbs or pipes 129, the first regulator or thatdisposed over the cylinder 101 lnwing1 two upright tubular limbs orpipes 129 and 130 with an intermediate air chamber 131. all incommunication with the elbow, the elbow 128 over the cylinder 102 haringsimilar upright tubular limbs or pipes 132 and 133 with an intermediateair chamber 13-1, all in communication with the adjacent elbow 128 andthe elbow 128 over the third cylinder 103 having upright tubular limbsor pipes 135 and 136 and an intermediate air chamber 137. The uprighttubular limbs or pipes 129, 132 and 135 are connected to the conduit orpipe 99, each of the tubularlimbs or pipes just mentioned,

prevent back pressure and back 110W from the cdnduit or pipe 99 into theseveral u right limbs or pipes 129, 132 and 135. The upright tubularlimbs or pipes 130,133 and 136 constitute vertical cylindrical chamberseach edntraeted at its lower extremity, as at 110, 'to forni a valvevseat for a valve 141 haring a stern 142 and secured to an. upperadjusting pluto` 143 between which and the valve 111 a spring 144surrounds the stem. 142 and 'causes the valve to be normally seated andto close an outlet 145, the outlets oil the respective upright tubularlimbs or pipes or cylii'iders 127 pipes 116, 'i4-7 and 1118 respectivelyconnected thereto and extending downwardly and joined to thesul'iplypipes 117, 118 and 119 and whereby an excess or overflow and eireulationof the liquid entering the several chambers 113 of the cylinders 101 to103 inclusive may be forced back to the source of supply. i The airchambers 131, 134 and 137 operate in conjunction with the chambershaving' back 110W.

after the. manner of the compressed air cylinders of ordinary pumps andmaintain a proper working pressure. When the pressure exceeds a desirednormal pressure the 5 valves 141 of each regulator will be automatically opened to clear the outlet 1-13 and permit of an overflow backthrough. the respective pipes 116, 117 and 118 to the pipes 117,r 118and 119 and whereby the fuel `0r .10h fuel material fed to each chamber113 of the cyli'n( l,ers 101 to 103 will be returned to its vvpropersource of supply.

It will be understood that the springs lll-1, cooperating with all ofthe valves 111, will be set or adjusted to resist a certainpredetermined and desired maximum pressure so that the valves 111 willnot open except when an excessive pressure is reached. 1t will be seenthat the short tubular limbs or pipes 129, 132 and 135 are so joined tothe conduit or pipe 99 that the fuel or fuel con- 'lstituents forcedinto the tubular limbs or pipes '1132, 135 may be cut-oft from 'the fuelor fuel' element forced through the limb or pipe 129 by properlyadjusting the threeway valve 190 and when the latter valve is so adjListed communication will be established between the limb or -pipe 129and 'the common feed or supply pipe 91, and under such conditionsgasolene from the source 122 will be pumped upwardly into the .conduitor pipe 99 and the feed pipe 91. When the valve 100 is adjusted toshut-oft communication between the limb or pipe 129 and the pipe 90, thelimbs or pipes 132, 135 will be opened to the pipe 80 and under theseconditions kerosene or distillate will be forced upward through the limbor pipe 182 and water will pass through the limbv or pipe 125 andbemiXed in suitable proportions accordin, ,0 to the adjustment of theneedle Valves 138 and the mixture then forced from the conduit or pipe99 upwardly through the feed pipe 91. The control of the fuel or fuelelement or constituents and water will be regulated by thc adjustmentsof the supply valves 126 and during the periods when the gasolene is notused its pumping' pistou and cylinder will be inactive as a means forraisingc;` or forcingthe same upwardly into the conduit or pipe 99 andfeed pipe 91` and conversely when the kerosene or distillate piston andcylinder and the water diluting' piston and cylinder are in operationthere will be no mixture of the `asolene therewith as the ,L'asolenesupply and pumping` means therefor will then be cutoff. The chamber ofthe eylinder 105 is somewhat larger than the chambers of the cylinders101 to 103 inclusive and likewise the pistou 1,12 of this enlargedcylinder is of similar and large proportions, this part of the pumphaving the water main or enlarged watcrsupply pipe 121 connected to thelower portion thereof and also pro c vided with a similar enlargedoutlet 149, a check valve 150 being introduced between the outlet pipe129 of the chamber of the cylinder The groups of cylinders. 5, 7 and 9and 6, S and 1G and a portion of the upper reduced extensions of thewalls are provided witi aA water chamber construction, as at 151 and thepipe 111-9 is connected to this water jacket construction, the checkvalve 150 preventingl back flow of the water forced upwardly by thcpiston of the cylinder 105. It will be understood that the water jacketconstruction will be supplied with a suitable outlet or return piperunning back either 8G to the tank'or source of supply 125 or to someother point as may be desired, so as to complete the circulation of thewater through the water jacket construction and maintain the cylindersand the upper portions of the wall extensions at a tempera-- tureadvantageous to the operation of the motor as a whole.

The fuel, either gasolene, kerosene or distillate and water passes fromthe pump by 90 way of the pipe 91 to the receiver 87 and rises in thelatter until the. air pressure in the upper portion of the receiverbecomes sufficient to force the uid from the receiver into the chamberG1 where it connning'les with t-he compressed air, the air pressure inthe upper portion of the receiver forming a flexible air cushion whichwill cause a continuous spray of fuel into the said chamber G1 and whenthis pressure is reached in the receiver' the fuel passes almostdirectly to the motor `chamber' 61, by way of the pipe 92, and from thefuel supply pipe 91 until cut-off by the three-way valve 100, and in theevent of excess pressure being generated during this operation in thepipes 91 and 92 sufficient to overcome th'e resistance of the spring 97,the valve 96 `will open and permit of an overflow through the pipe 95,said overflow running back to the pipe 117, if gasolenc' is used, as thefuel, or by way of a' branch pipe 152 back to the pipe 118, if keroseneor distillate and water are used, a l valve 153 being disposed in thepipe 95 below the pipe 152 and between the latter and the supply pipe117 and whereby kerosene or distillate and water may be prevented' frompassing into the gasolene source of supply 122 an d insure a return ofthe kerosene or distillate and water to the pipe 118 and then into thesource of supply 123.

It will be understood that 'by Aadjusting` the needle valves 138 anyamount of gasolcne, kerosene or distillate and water may he permitted topass to the conduit or pipe 99 as may be necessary to provide anadvantageous fuel or fuel mixture' which is A finally fed by the pipe;toV the 90 and ieceiver'S?, or, under the conditions just specified,almost directly to the chamber 61 of the motor or engine through thespray pipe 92.

Each group of motor orl engine cylinders and pistons will be supplied`with spark plugs 137. These plugs in the cylinders 5, 7 and 5) (whichin the present instance are arranged as the internal combustion ordriving cylinders) are disposed at the right of the upper portions ofsaid cylinders .in the same position in all of the cylinders of thisparticular group, and at a point about opposite to the posit-ion of thesparking plugs 137 in these driving cylinders the casings of thecylinders are'each provided with an' exhaust outlet 138 communicatingwith an exhaust pipe or passage 139 which is formed by boring throughthe cylinder casings and intervening Walls to the central dividing wall13. 'In the group of cylinders G, 8 and 10 (which in the presentvinstance are shown arranged as compressing cylinders) the sparkingplugs are at the leftof the several cylinders and the exhaust outlets138 and exhaust bore or duct 139 are located at the right so that therewill be no interference with th passage of the compressed air from thecylinder chambers into the chambers 61 and 62 above. The exhaust ductsor passages 139 may communicate with a common outlet pipe 140, asshownby Fig. 4. The operation of the spark plugs 137 will be controlled bymeans of a suitable timer so as to render either one of the groups ofspark plugs active in accordance with the direction of movement of theshaft 18 and pistons 19 that may be desired, and in reversing themovement of the pistons in the respective cylinders it is only necessaryto cut off the one group of spark plugs and render active the remaininggroup or groups of spark plugs.

Each of the needle valves used in connection with the improved motor orengine and pump organization associated therewith is of the samestruct-ure and one of them is shown in section by Fig. 14 and comprisesa casing 154 with an-inlet 155, an outlet 156 and an intermediate valveseat 4web or member 157 with a. tapering bore 158 forming the means ofcommunication between the inlet 155' and the outlet 156. A plug 159 isrotatably mounted and secured thereto in the necked portion 160 of thecasing and is provided with :n.tapered extremity 161 to engage the bore158 of the valve scat 157. As hereinbefore indicated this valve may be 4positioned either with the plug 159 in up right position or inhorizontal position and in each position the operation will be precisely the same and the quantity of fuel or fuel mixture passingtherefrom will depend upon the amountl of exposure of the bore 158 bythetapered extremity 161 of the plug 'through the )assages `tll the chargeis exposed dotted lines in chambers 61 and 62,-

trolling valve 69 will have closed the will be ofsuitable 4type and ofthe most improved form adapted to perform the functions of such devicesat the points where they are installed.

The operation of the motor or engine is simple and when it is l`desiredto start the same the supply of mixed air and fuel will betransniitted'- from the tanl; S() by means ofthe pipe 83 to the valvechamber 59 and through. the'medium of the Valve 69 will be regularlydischarged 60 into the cylinder chambers 16 ehindv the abutments 39 andagainst the portions of the pistons exposed by the lsaid abutments andoperate to force the 4pistons around in regular succession unto theaction of the spark plugs when the usual explosion will ensue and thepiston lie-driven around and the exhaust effected through the outlets13S. After the engine has started, the gasolene may be supplied to thechamber 6l by means of the pump and pump organization and connectionshereinbefore explained, and after the cylinders have been fully heatedthe gasolene supply will be lcut olf and the keroseney or distillate oflower volatility with water will be supplied to the receiver 87 and fromthe latter tothe chamber 61.

here Vis no communication between the the chamber 62 being an airreceiving and 'storing chamber andl charges of the fuel are regularlydelivered by the channels 7l, and ahead of these c larges of fuel aprotective air cushion is provided by charges of air from the chamber 62carried around by the channels 70. The admission of chargesof air bymeans of the channels 7 0 into the cylinders ahead of the charges offuel mixed 'with air which are safety to avoid any l of prenlatureexplosion, and though a premature explosion in this particular motor orengine would not cause any damage, as the pistons are always rotating inone direction, the effectiveness of vthe engine is much better when'there is no premature explosion. Briefly consideringthe position of thepistons as illustrated in Figs. 4 to 6 inclusive, relatively to thecompression cylinders, as shown by Figs. 7.to 9 inclusive, it will beunderstood that, as the first cylinder of the left is charged n tweenthe latter and the 39 around to the sparking plugs, the piston in thecompressing chamber to the extreme rightwill have justconipleted itscompression' operation or stroke vand will have closed the swinging.abutment 3S) thereinto a'nd at the same time the rotating conpassagewayleading-from the combustion chamadjacent abutment or reservoir bers 61and 62.

Thepiston continues to rotate until it cannot close the i abutment,A whentlielatter will gradually open into the position shown by Fig. f-,t andpermit a re-chai'ge of the cylinder, the abutment following around onthe surface of the piston as clearly indicated by Fig. 5 during therotation of the said piston and there*- `'charge until the'latter lpower or impelling force against the piston.

The niotor orengine as hereinbefore described is also powerful in its operation andis comparatively compact and may be effectively used for the p.vfticular purpose for which it has been devised.
